EAR-RING.

SPECIFICATION forming part of Letters Patent No. 397,433, dated February 5, 1889. Application filed March 18, 1886. Serial No. 195,727. (No model.)

which bears on a corresponding knife-edge in an eye or staple secured to the ear-ring loop or other article.

The novel features of my invention above briefly pointed out are more fully described in the following specification, and claims, and

illustrated in the accompanying drawings, in

which Figure 1 represents a sectional side elevation of an ear-ring embodying my invention. Fig. 2 is a front elevation of the same. Fig. is a rear elevation of the setting. Fig. 4 is a sectional e'le 'ation, on alarger scale than the preceding figures, showing the suspendin g-eyes in a slightly-modified form.

Similar letters indicate corresponding parts.

In the drawings, the letterA designates the loop of an ear-ring, and B is the setting, all constructed as usual. The loop A, Figs. 1 and 2, is provided at theproper point with an eye, 0, which has therein a knife-edge, This knife-edge is made of hard steel, iridium, or some other material, as ruby, which will retain its keen edge, and it may be secured in the ring by the use of solder or in any other manner; The settingl) has thereon a staple, (I, which is provided with a knife-edge, 1) in its upper portion, the apex of which latter points downward. This knife edge is arranged to bear at right angles upon the knifeedge C in the eye (2 when the eye and staple are interlocked, so that the setting is suspended by the knife-edges. be struck up integral with the setting, or it may be secured thereto subsequently. In place of such a staple (Z, an eye, cl, Fig. at, maybe used, which then secured to the setting.

The object of my invention is to procure a setting which is suspended with the least possible friction of the parts in contact, so that the diamond or other stone in the setting will The staple can be allowed. toswing freely, and thus be in an incessant tremor, whereby the stone is caused to appear more brilliant. A setting so suspended is not liable to be lost by wear, as with ordinary settings, since the parts in contact are made of a hard material whichis not liable to wear appreciably. It is apparent that settin can be also suspended from brooches, lace-pins, and the like in precisely the same manner.

\Vhere the invention applied to abroocli, lace-pin, or other article of jewelry, the brooch or pin will. constitute a base as an equivalent for the loop, and the eye 0, having the knifeedge U, will be attached to such. base, instead of to the loop. The knifeedge will of course be of any appropriate form suitable for the conditions required.

I make no bread or generic claim in this case to a pair of knife-edged bearing-sun faces, as such broad claim is set up in my other case, Serial No. 200,832; neither do I design any of the claims in this case to cover any matter herein shown and described, but embraced in any of the claims of my said other case, Serial No. 200,832.

\Vhat I claim as new, and desire to secure by Letters Patent, is-

l. An article of jewelry ctmsisting of a loop or base having a knife-edge, C, and a suspended setting, ll, having a knife-edge, .D, extending across and bearing on the other knifeedge, substantially as described.

2. The combination, with the loop A, the eye 0 thereon, and the knife-edge C in said eye, of the setting B, the eye or staple there of, and the knife-edge Din said eye or staple, which bears on the knife-edge of the eye 0, substantially as shown and described.

3. The combination, with a loop or base and a setting, of the interlocking eyesprovided with knife-edges in contact at right angles, one eye being secured to the loop or base and one to the setting, substantially as shown and described.

In testimony whereof I have hereunto set my hand and seal in the presence of two subscribing witnesses.
